another spinner (with 8mm nut, 22 od bearing)

i got bored enough to make one of these in design spark as a way to learn the new (new to me) software. there is a version with holes for a 8mm nut.
you need to print 2 plugs or use another plug from another model.
let me know if tolerances are too tight i am yet to print one so let me know how it works out
